Abstract

The present invention discloses a kind of Wheat wide Precision Seeding cultivation technique, belongs to technical field of crop cultivation.The specific steps that the technology includes have：The selection of kind, culture fertility, deep ploughing subsoiling, preventing and treating subterranean pest-insect, optimum period fertilizer spraying.Wheat wide Precision Seeding cultivation technique is standardized, become more meticulous by the present invention, and its small investment, high efficiency, operation is simple.

Description

A kind of Wheat wide Precision Seeding cultivation technique

Technical field

The invention belongs to technical field of crop cultivation, and in particular to a kind of Wheat wide Precision Seeding cultivation technique.

Background technology

Wheat wide Precision Seeding cultivation technique be in essence amount, on the basis of semi-accuracy seeding technology, with expand sown scope, line increment away from, Promote it is even broadcast as core, change the agricultural machinery that intensive drilling is wide cut Precision Seeding and the high-yield culture technique that agronomy is combined.

The content of the invention

The technical problems to be solved by the invention are the deficiencies for existing wheat cultivation technology, there is provided a kind of Wheat wide Precision Seeding cultivation technique, its small investment, high efficiency, operation is simple.

To achieve these goals, the present invention is achieved using following technical scheme：

A kind of Wheat wide Precision Seeding cultivation technique, including following specific steps：

1. the selection of kind：More than 300-400 kilograms of high yield can be reached from high yield potential, rate of tillering panicle height, per mu yield High-quality medium fringe type or Multi spike cultivar.Every mu 15~180,000 Basic Seedlings;The high middle fringe type kind of rate of tillering panicle, every mu basic Seedling 12~150,000.The high seed coat agent of quality is selected to carry out seed pelleting before broadcasting.Such as No. 4, Jinmai 49 are educated in Gansu Province mirror 386, Gansu Province.

2. culture fertility：Adhere to fertilization compositions based on earth measurement, pay attention to straw-returning, increase chemical nitrogen fertilizer, culture fertility；Take Machine inorganic fertilizer is combined, and nitrogen, phosphorus, potassium balance fertilising, increases micro- fertilizer.16 kilograms of time of infertility mu nitrogen topdressing, phosphorus（P2O5） 7.5-12 kilogram, potassium（K2O）7.5 kilograms, 1 kilogram of zinc sulfate.By organic fertilizer, phosphate fertilizer, potash fertilizer and 50% nitrogenous fertilizer of whole, make Disposably applied for base fertilizer.Notice that the plot of straw-returning can not have to impose potash fertilizer.Second Year, wheat period of seedling establishment impose again 50% nitrogenous fertilizer.Chemical fertilizer wants deep placement, prevents earth's surface and spreads fertilizer over the fields.

3. adhere to deep ploughing subsoiling, plough and harrow supporting, attention preventing and treating subterranean pest-insect：The thin rake of deep ploughing, makes vola moisture in the soil.Tilling depth 23~25 Centimetre, break plough sole, do not balk, ploughing rake thoroughly thoroughly, increases soil water storage soil moisture conservation.Deep ploughing will combine closely with thin rake, nothing Light and shade clod, reach Panasonic's reality;Put down after ploughing, carefully put down after bedding again, ensure that watering is uniform, do not rush and do not become silted up.Soil moisture content deficiency Should broadcast preceding moisture creating.

Because nearly 2 years subterranean pest-insects are increased, particularly wireworm harm is serious, it is proposed that first with phoxim particle formulation poison Soil, spread fertilizer over the fields during arable land, prevent to do farmwork for a soldier's family to revolve, at least to ensure every 1-2 deep ploughings once.4. adhere to optimum period fertilizer spraying：Date of seeding In 15 days-September of September 20 days.The amount of broadcasting is at 6-9 kilograms.Sowed using 2BJK series Wheat wides precision planter.Change the small row of tradition Away from（15-20 centimetres）Intensive drilling is to wait line-spacing（22-26 centimetres）Wide cut is sowed, and depth of planting is strict controlled in 3~5 centimetres, 6~8 centimetres of sown scope.Change the intensive crowded line of drilling seed of tradition to broadcast for the wide sub- distributing grain of sowing, be advantageous to seed distribution Uniformly, without the disconnected ridge that is short of seedling, without pimple seedling, the intensive drilling of traditional seeder is overcome, seed is crowded, strives fertilizer, strives water, strives nutrition, The upgrowth situation that root is few, seedling is weak.

5. during wheat growth, do prediction well：Preventing and treating pest and disease damage in good time, is especially carried out to aphid, red spider, white powder The preventing and treating of the pest and disease damages such as disease, rust, banded sclerotial blight.

6. early spring intertills Meteorological effect, promotion, which is turned green, imposes urea.

7. Nitrogen Top Dressing suitably moves afterwards, pay attention to foliage application, delay plant senesecence, it is anti-in time that the later stage carries out " a spray three proofings " Control various pest and disease damages.Delay wheat plant aging, be finally reached regulation and control colony and individual contradiction, coordinate fringe, grain, weight three pass System, the target of improving yield of wheat is reached with higher biological yield and economic coefficient.
